Mefenamic acid can cause severe intestinal damage that looks like coeliac disease. Stopping the drug quickly resolved symptoms in patients, showing a direct link between the medication and intestinal injury.

Area of Science:

  • Gastroenterology
  • Clinical Pharmacology
  • Drug-Induced Diseases

Background:

  • Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used for pain and inflammation.
  • NSAID-induced enteropathy is a known complication, but severe cases mimicking other conditions are less common.
  • Mefenamic acid is a commonly prescribed NSAID.

Observation:

  • Two patients presented with severe intestinal damage.
  • Clinical, radiological, and histological features mimicked coeliac disease.
  • Symptoms were directly linked to mefenamic acid use.

Findings:

  • Mefenamic acid induced severe intestinal damage in both patients.
  • Withdrawal of mefenamic acid led to rapid symptom reversion.
  • One patient remained symptom-free when treated with other NSAIDs, suggesting a specific drug effect.

Implications:

  • Mefenamic acid should be considered in the differential diagnosis of severe intestinal damage, especially when coeliac disease is suspected.
  • Physicians should be aware of the potential for NSAID-induced enteropathy to mimic other gastrointestinal conditions.
  • Further research into NSAID-induced enteropathy mechanisms and management is warranted.
